The foot levez' 18 is con,u nested to the turret heed l by meens oi" the linl': lfl. lt will be seen that by this een rangement o. straight down pull imported to the turret heed so thet eithee e soecesing etlect o1` s. sharp hemmen blow tney be obtained subject 'to the forcee 'with which the pedal i8 is oct-usted.

Up and down movement is imparted to the drilling mechanism C by ineens ol" the motor lil-t pedal "lo connected thereto by means off-the link lid-Which is offset es shown et lil (see Figi?) to avoid interference with the op? eration of the toot levetl i3.

ln the turet heed B are mounted e nurnbei of tools io this case four, namely., e lfivet iivet header. The tuYet is mounted to' tev volvo on the pin 19 and isprovided with, e catch 20 adopted to engage one of e. series of four notches for the purpose oi' holding` e5 in positiouthe tool selected tot` usec deg sheer, a nivet drift, drill locator and o.

and l0. rThe body cestingjrl is plovioled l es shown in i.

with an automatic switch 2l which operates start the, drill motor 22 whfenthe-motor pedal 16 is'depressed. As the drill nears upper position it engages a vstop 23 which y he adjusted for diherent classes vof work.

l The operation of the device is as follows: .lbrake band is placed on the work table liig. l, by straddling it over the upper hcdy' of the machine and the turis revolved to hring the rivet shear in the position indicated. The hand isheld iirmly by the operator and then a sharp blow or a succession of sharp blows is given to the foot lever/713 which shears oif the rivet heads. The hand is then placed on the work table in the" illosition shown in Fig. B in which position alie band is pendent on the tahle and straddles it and the drilling mechanism C, the turret head revolved to bring the rivet drift in position and the lever again actuated to remove the rivets, and then the worn lining is removed and the band is in condition t'or relining. The band together with the new lining which may be clamped to it isnow placed on the work tahle straddlingit. and the drilling mechanism in the previous operation and the 7 drill locater is brought into position as shown in Fig. 4 for the purpose ot aligning the holes with the drilling mechanism C. The drill locater is provided with a angle point which is centered in the hole already provided in the steel band which insures accurate alignment with the drillmechanism C. Then the foot is released from the lever 13 which returns to its normal position by means of the spring 24, and placed on the pedal 16 which raises the drilling mechanism until the stop 23 is engaged. The depth of the drilling may he regulated by adjusting the stop It is to he ohserved that the drill is a combined drill and countersink so that the rivet may be set in from the surface oit the lining.

titer many holes have been drilled as are deemed necessary the operator proceeds to insert the riveting anvil 25 in the hole provided for it in the work tahlc. This anvil is provided with a looss 2G which pro jects into the countersunk portion of the holes in the lining. The hand is now lifted clear ofthe anvil-(still straddliug the Worli table and drilling mechanism)` a rivet in.

sorted and then positioned on the anvil, the lioss finding itself in the countersunk hole and insuring even contactwitlrthc rivet head, at the same time aligning the band with respect to the turret head. The rivet header is now liro'ught into position (see Fig. and the lever 13 actuated, thisA time with a sharp kick wlii ch forms a head on the rivet. in this connection it is to he observed that the lever 13 is pivoted well at 'the top t n drilling,v mechanism C is provided 'f totore used for this purpose.

ofthe machine so that the momentum of machine I am enabled to use solid rivets.

which is not the case with the machines here- While I have described my device in connection with brake bands having the lining on the inside it is to be understood that it is also applicable to bands having the lining on the outside as well as to flat disks', such as clutch disks. As shown by the dot and dash lines in Fig. 2 tlie bands may be just as readily placed in the machine either in pendent or upright position as would he the case where the lining is on the outside ot the band, the turret head beingso disposed so that the band straddles it when supported on the table in upright position.

When relining the facings of clutch disks as shown in Fig. 6, the mode ofv operationis slightly diierent. The work table D. pro# jects in such. a manner that the clutch disk' may be placed over it on edge for the purv pose of shearing'the rivet, which operation and the rivet dislodging operation are exactly as described for brake bands. After all the rivets have been punched out and the worn tacings removed a on the under side of the metal disk and one hole is drilled and a rivet inserted without forming a head to act as a dowel to hold the new lining is placedfacing in place while drillin the balanceof the holes, which is accomplis ed in the same manner as described in connection with brake bands. The facing is now placed on the other side of the metal disk, turned over and drilled, the 45 drill locator being brought into engagement with the holes previously drilled in the first facing. The rivets are now inserted and secured in place. So that the work table may present adquate surfaces forvarious classes of work it has been provided with a iiat portion 28 for flat Work and with the curved portions 29, 29 for curved work.

lt' will be seen that h'yhaving a specially designed fined work table located between a turret tool holder and a drilling mechanism the former being aboveA the table and the latter` below, it is possible to perform all 0f the necessary operzttionsfor relining brake machine. Such arrangement has enab ed me to provide an eiectiveiriveting action for various t-ypitt or rivets.
